What Is Stainless Steel?

303 A non-magnetic stainless steel specially designed for improved machinability.
304 Chromium-Nickel austenitic alloy used in a wide range of applications.
304L Chromium-Nickel austenitic alloy used in a wide range of applications.
316L Molybdenum bearing austenitic stainless steels which are more resistant to general corrosion and pitting/crevice corrosion.
317L Molybdenum bearing austenitic stainless steels with increased resistance to chemical attack compared to standard chromium-nickel austenitic stainless steels.
317LMN 317L + increased levels of moly and nitrogen for enhancing resistance to pitting and crevice corrosion.
304H Modification of 304 in which the carbon content is controlled to a range of 0.04 – 0.10 to provide improved high temperature strength.
321/321H A stabilized stainless steel which has excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F.
347/347H Stabilized stainless steel which offers excellent resistance to intergranular corrosion following exposure to temperatures in the chromium precipitation range from 800 to 1500°F.
309/309S Austenitic stainless steel used in applications where elevated temperatures are present.
310S Austenitic stainless steel used in applications where elevated temperatures are present.
410 Hardenable, straight-chromium stainless steel which combines superior wear resistance with excellent corrosion resistance.
410S Low carbon non-hardening modification of 410. Resists cracking when exposed to high temperatures or in the as-welded condition.
LDX 2101 Low nickel lean duplex stainless steel possessing both superior strength and chloride stress-corrosion cracking resistance when compared to 300 series stainless steels.
2304 A high chromium-low nickel-moly free duplex stainless steel exhibiting improved strength and stress corrosion resistance properties compared to 304/316 austenitic stainless steels.
2205 A high chromium-nickel-moly duplex stainless steel providing high strength and superior resistance to general, local, and stress corrosion compared to 316L or 317L.
2507 A chromium-nickel-moly super duplex stainless steel with exceptional strength and corrosion resistance in the chemical process, petrochemical, and seawater environments.
17-4PH Martensitic stainless steel that is capable of precipitation hardening. This stainless steel has very high strength and hardness.
SSC-6MO Superaustenitic 6% molybdenum alloy that exhibits superior resistance to chloride pitting, crevice corrosion and stress-corrosion cracking when compared with the standard 300 series and duplex stainless steels. Premier corrosion resistant austenitic stainless steel.
